Hi I have just inherited a PC from a user that is having boot issues. The users states they were happily using the computer when they lost visual and since have not been able to recover it. When the PC initially boots it turns itself off after about 5 seconds and then reboots and seems to be running fine (it doesnt turn off again) I have check the seating of components and all seems clear. There are no Beep codes being transmitted and the system seems to be running fine as far as cpu and case components running. There is just no visual.
I am thinking that the user may have mis-configured the case wiring that is why there is reset behavior when the PC is powered on. I do not have a PCI Express Video card but will be purchasing one tomorrow as I feel there may be an issue with the card.
I feel the system needs a bigger power supply as it has 8gb of Kingston DDR800 (2x4gb modules) 2 sata hdds, 2 case fans, DVD burner and a Gigabyte Geforce 9800GTX+ Video Card with an Intel Quad Core Processor. The power supply fitted in the machine is a Cooler Master 460W (460-PCAR-A3)
I will be looking at the pc more thoroughly but thought I should post details because I have done similar on this site before and have found the information offered by techies invaluable. So if anyone has any clues on this one I would be most appreciative.
